Not with Photoshop 6. If you take a monitor profile and make it the RGB
Working Space, you may or may not have a gray balanced working space. It
depends on the profile. Ideally the monitor is gray balanced during
calibration such that the monitor profile describes a gray balanced
monitor, and in that case, using this kind of monitor profile will yield
a gray balanced working space. But this is not a guarantee like it was in
Photoshop 4 and 5.

If you use a non-gray balanced space as a working space (for example
specifying an inkjet printer as the RGB working space), you will end up
with a non-neutral editing space. Gray balancing your images will have to
be done stricly visually. Theoretically the monitor preview is still
accurate and will show this lack of neutrality, but monitor soft proofing
is far from perfect so I do not recommend using profiles that describe
poorly behaved, non-gray balanced color spaces.
